Chlorophenol red ph range
Did you know?
Chlorophenol red is an indicator dye that changes color from yellow to violet in the pH range 4.8 to 6.7. The pH of a substance is determined by taking the negative logarithm of the Hydronium ion concentration and the indictor changes color due to the dissociation of H+ ions. The lambda max is at 572 nm. WebChlorophenol red is a widely used pH indicator dye that changes color from yellow to violet in the pH range of 4.8 – 6.7. It is utilized as an optical transducer of acetyl cholinesterase inhibition by the analytes and also used to selectively determine chlorine dioxide in drinking water.
